Bad service from shoprite

Shoprite Mayfair is the worst store to ever shop at. Firstly the managers there dont give a damn about customers, secondly they are aware that it gets busy at a certain time but every day there's only two cashiera or three cashiers out of 7/8 tills only 3 operate which is ridiculous. The staff there are ruse as hell as if I sent them there to work same goes for shoprite Newtown Junction so many tills but only 2 operate. I don't understand is it a shoprite thing or what. Please train your staff and get them in order it's very frustrating to be standing in a line for 30mins where as there are other operating tills available.
